Black hole: A Region with Accelerating Gravity
Author(s): Bobir Moumni*
A black hole is a place in space where gravity pulls so hard that even light cannot escape from it. Gravity is so strong
because matter has been compressed into a tiny space and does not allow the smallest particles, electromagnetic
radiation or space objects such as comets or planets. This can happen when a star dies. Stellar-mass black holes are
formed when a massive star can no longer produce energy at its core. Black holes can be millions or billions of stars or
as small as a few stellar masses that are crushed to extreme densities in supernova explosions. They are invisible.
Space telescopes with special tools can help find black holes. Special tools can see how stars that are very close to
black holes behave differently than other stars. The star's outer layers can be blown out into space or fall into the
black hole to make it heavier. When a black hole and .. View more»
